This paper examines the history of asteroids' discovery and analysis and offers a consideration of Potentially Hazardous Asteroids (PHA) and asteroid impacts. The paper reveals that now, asteroids are treated as both a scientific resource and a potentially catastrophic threat. The paper shows how human perceptions of asteroids have changed as scientific understanding and technological change have evolved.

From the Paper:

"The 'Celestial Police', an organization of astronomers, initiated a search for the missing planet. Assuming that the 'missing' planet would also appear along the ecliptic it was divided into 24 sections and each astronomer was assigned a portion (or 15 ). In January 1801, one of the Celestial Police, Giuseppe Piazzi reported he had discovered an object that moved somewhat like a comet but was "not accompanied by any nebulosity and that its movement is very slow and rather uniform has caused me many times to seriously consider that perhaps it might be something better than a comet." It was not a comet; it was Ceres, the first asteroid to be discovered.
"It took a year to confirm the existence of Ceres yet within another three months Heinrich Olbers identified a second asteroid, Pallas. Olbers was also the first to propose that asteroids were detritus from a planet that had once existed between Mars and Jupiter. He asked of William Herschel, "Could it be that Ceres and Pallas are just a pair of fragments, or portions of a once greater planet which at one time occupied its proper place between Mars and Jupiter...either through the impact of a comet, or from an internal explosion, burst into pieces?" However, after the discovery of Juno and Vesta (for a total of four) no more asteroids were discovered for almost forty years."
